We make a lot of cocktails around here, so I have several simple syrups in the fridge such as honey, ginger, plain sugar, etc. Since we have been a a margarita kick this summer, we have not used them. Some syrups are past one month in age. Can I still use them? Most sources say to store for 1 month, but since it's just sugar & water, is the one month timeframe a quality thing or a safety thing? They smell fine and I hate to discard.
